SPECIFICATION forming part of Letters Patent No. 31%,609, dated March31, 3.885.

Application filed November 10, 1884.

To all whom it may concern:

Be it known that I, JOHN G. F. SOHENOK, a citizen of the UnitedStates,residing at Moline, in the county of Rock Island and State ofIllinois, have invented certain new and useful Improvements inAttachments for Flows; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification.

This invention relates more particularly t that class of attachments forplows known as pulverizers; and it consists, essentially, in thecombination, with the mold-board of a plow, of a cutter arranged torotate in a plane practically at right angles to the plane of motion ofthe plow, said cutter being applied to the under edge of the heel end ofthe moldboard, substantially as hereinafter fully described, and asshown in the accompanying drawings, in which- Figure l is a sideelevation of a plow embodying my improvements. Fig. 2 is a like viewshowing a driving mechanism connected with the pulverizer, and amodified arrangement of pulverizer. Figs. 3 and 4 show modifiedconstructions of pulverizers.

In the above drawings,B indicates the draftbar, H the handles, S theshare, and M the mold-board, of an ordinary plow.

On the under edge, at the rear end or wing of the mold-board, are formedor secured two bearings, 13 B, in which are pivoted the journals of apulverizer, which, as shown, is a spiral or twisted cutter, O, the edgesof the spirals or the twist being made sharp, so that when the slice isbrought in contact therewith said blade will cut it and break it up. Itwill be seen that when the slice passes over the rear portion of themold-board and is turned it will come in contact with the cutter, and itwill be cut or broken up, the cutter rotating at the same time to throwthe broken slice off.

In heavy soil the cutter will be rotated by (No model.

soil it may be desirable to employ mechanism for rotating the cutter. InFig. 2 I have shown such mechanism, which, as will be readily seen, maybe applied to wheel-plows. W indicates the ground-wheel,that has itshearings in hangers secured to the handles H. The shaft of the wheelcarries a pinion, 19, that meshes with a transmitting-pinion, p, thearbor of which carries a bevelpinion, P,.that meshes with acorresponding pinion, P,oin the cutterjournal.

In wheelplows the cutter may also be ro-V tated by connecting the samewith one of the groundwheels by means of chain-and-sp rocket gearing orin any other desired manner.

I have above described a cutter, C,composed of a twisted or spiralblade. It is obvious, however, that good results may he obtained bymeans of a fluted roller, Figs. 2 and 3, the cutting-edges of which arepreferably arranged spirally.

Instead of a fluted ioller, a roller, 0, Fig. 4, provided withbarrow-teeth arranged in concentric circles or spirally around theroller, or a fluted roller, 0, Fig. 3, having such teeth applied in thegrooves between the cuttingedges, may be employed.

The attachment is applicable to all kinds or styles of plows in which amold-board is used, and the dimensions of such cutter will naturallyvary with those of the plow to which such cutter is applied.

Having now described my invention, what I claim is Thecombination,substantially as described, with the mold-board M of a plowand agroundwheel, of the pulverizer O, of equal diameter throughout itslength, journaled in bearings B B on the lower edge of the heel or wingof the moldboard, and carrying a pinion and intermediate gearing forrotating the pulverizer from the ground-wheel, for the purposesspecified.

In testimony whereof I affix my signature in presence of two witnesses.
